I had my crab apple tree sprayed a few times professionally for any fungal problems; however, the leaves have an odd growth on them. I've attached some pictures of the front and back of the leaf. Any ideas??

Looks like apple scab, a fungal disease common on crabapples. It is generally not harmful to the tree unless allowed to continue for years. Best way to combat is by good sanitation at the end of the season; rake up all leaves and remove fruits if possible. In the spring a fungal spray applied according to directions. There are several sprays available. Look up apple scab treatments for a thorough explanation.
